1,014,396. DUMP-GAR. Ma iqtis L. llvma,

Chicago, 1ll., assignor to William D. 0rd, Land rall', \V. Va. Filed Oct. 15, 1010. Seria No. 587,169.

In all whom it may concern:

Be it known that I Martens L. H irnn, a citizen of the United States, residin at= Chit-ago, in the county of Cools and tate of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

My invention re ates to a dump car de signed more particularly for use in discharging materials such as coal, ore, stoneg I 010., from trains made up of any number 0 cars and when in motion. O

In the drawings accompanying the spcci- I tication Figure 1 is a side elevation of a car, embodying one form of my invention, aboutto be dumped; 'ig. 2 an end view thereof in the direction f the arrow of I ig. 1; big. 3 a longitudinal section of the car in dumping osition; Fig. 4 a plan of the truck w th the iody of the ear in dotted lines, and Fig. I) a detail of a modification.

Similar reference numerals indicate simi' lar parts in the several views.

In the construction shown, the car comg prises ii flat truck having side members 1, 3 end members 2 and bum blocks 2 eecured together and braced in a suitable mannor to form a support or letform for the body. The truck I earn oirexlee 8 end 3 and wheels 4, suitable bearings being pro- I vided for the axles on the side members 1.

The truck frame projects beyond the wheel base at both ends an amount sullicient to permit proper coupling to adjacent cars.

the mat of rotation of the car body and the disc iarge end is free from an internal bracing to permit the rotation o the discharge end of the car between the sides and end member of the truck.

The body of the car com irises a bottom 6, sides 6, and a closed cm 7, these parts being secured together and braced as usual in car construction, and is supported by the truck frame a convenient construction being to (provide angle plates formin a brace for eai frame and a support for t 0 body. To increase the capacity of the car I may enlarge the cross section of the body between its point. of rotation and the closed end, as shown in Fig. 2 and by the dotted lines in Fig. 4. Secured to the under side of the bottom 6 are U-shaped pedestals 8, which, as shown in Fig. 3, engage the axle 3, the latter forming a pivotal su port around which the body may be partially rotated in a vertical plane. pwiird displace ment of the body is prevented by. bolts 9 passing through the dependent lugs of the pedestals, and ion itudinal displacement is prevented by eai lugs. Transverse displacement is prevented by collars 9' fast on by a gate 10 supported from the center of rotation of the body. On the sides 6 of the body, at the discharge end,

I provide guides 12 spaced snlliciently far apart to permit of the free passage of the. sides when the body is rotated, and suiticiently close to form a tight joint to prevent leakage. .Tliese uidcs may be formed in the body of the sides or by securing thereto separate pieces, and the grooves so formed receive the edges of the gate 10.

The car, so far described, may have p" vision made for dumping it in any suitable manner. I prefer, however, to effect an automatic discharge and have shown a slinple means for that purpose, consisting of attachments to the body at or near its closed end. As shown, these are in the form of wheels or rollers 13 mounted on a Cross shaft 14, supported in bearings in suitable brackets. These rollers are adapted to engage inclined rails 15 supported on appropriate structural work at the discharging point. The guide rails 15 am so disposed alon side of the trackwav at the place of disc er as to engage the wheels 13 and elevate e cloeed end of the body. effecting a sldlioieiil elevation of the body to insure coinplole discharge of the contents before the wheels 13 mss the summit of the guide. I'Zllln' IS. The latter, as shown in Fig. 31, are continued beyond the summitand inclined downwardly 0 as to client a gradual return of the body of the ear to its closed position,

That portion of the truck frame between the open end engaging the gate 10 to etl'ect the complete closure of the body of the car.

It the discharged material is to be conf vi'yi-d away from the point of discharge, l i provide a suitable chute or hop or for such purpose. In the drawings I owe shown the car discharging upon the bottom plate l i of a mechanical feeder.

Among the advantages incident to the construction above described are: first, a gentle discharge of the material, obviating ireakago of the contents and strain upon the car: second, rapidity of discharge; third, economy of operation in that. the cars do not. have to be detached from a train, each car disehargin as it engages the guide rails; fourth, a body so tight at all points as to prevent lcaka e in transit.

In Fig. 5 Iliave shown a slight modification in the point of rotation of the car body; Instead of having this point on one ofthe axles I have shown an independent,

axis parallel with the axle and located between the axle 8 and the discharge end, which construction may be advisable in certain applications. The pedestals and collars are the same as shown in Fig. 4.

What. I claim and desire to secure by Letters Patent of the United States is:-

1. A car comprising a truck having side and end members, a body-carried thereby, said body having an open discharge end, a pivotal support for said body and means for rotating the body about said support to lower the discharge end between the side and and members of the truck, a gate attached to one end of the truck, and means on the body adapted to eotiperate with means associated with the track way to lower the discharge end of the body away from said guide.

2. In combination, a car comprising a truck, a body carried thereby, said bodyl having a discharge end of less width than the truck frame, modes on the truck for clnsi ing the discharge end of the body, rollers 1 carried by the car, and an inclined track with which said rollers are adapted to eol o crate to partially rotate said body to disc arge the contents thereof and to restore it to closed position.

8. In combination, a car comprising a truck, a body carried thereby, said body having a discharge end of less width than i the width of the ruck frame, a pivotal aupport for said car carried by the track, an i inclined track, and means on the ear adapt- I ed to coiiperate with said track to partially rotate the body of the car in the longitudinal direction of the truck to discharge its contents and to restore it to its n rmal posilien on the truck.

4. In combination, a car comprising a I track, a body carried thereby, said body having a discharge and of less width than the truck frame, a pivotal support for saidhody carried by the truck, a trackway over which said car is adapted to travel, a receiver beneath the trae way, and means for lowering the dischar 0 end of said body between the side members of the truck, said pivotal support being so placed that the discharge end of the body, when lowered, will pass into the receiver.

a. In combination, a car comprising a truck, a body carried thereby, said body havin a discharge end of less width than the width of the truck frame, a pivotal support for said body carried by the truck, a gate attached to one end of the track and adapted to close the open end of the body when the latter is in normal position, a trackway over which said car is adapted to travel, a receiver beneath the tracltway, and means associated with the trackway to lower the discharge end of the body away from said (gate, said pivotal supgort being so place that the discharge on of the body, when lowered, will pass into the receiver.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
